An event generator for decays at NLO in SMEFT matched to a parton shower
Livia E. G. Maskos, Benjamin D. Pecjak, Shakeel Ur Rahaman +1
We present a Sherpa implementation of NLO corrections in dimension-six Standard Model Effective Field Theory (SMEFT) to the benchmark process . The calculation includ…

One-loop Effective Action up to Dimension Eight: Integrating out Heavy Fermion(s)
Joydeep Chakrabortty, Shakeel Ur Rahaman, Kaanapuli Ramkumar
We present the universal one-loop effective action up to dimension eight after integrating out heavy fermion(s) using the Heat-Kernel method. We have discussed how the Dirac operat…
